I have a 1.5W solar panel directly clipped to my RV battery for extended parking. Would this be the device for protecting from overcharging?

Sure it would work... but 1.5 Watt panel is not very much input in a car or truck battery. How much amp out put is that panel? Let me know... Don

Yes. Charge controllers, like this one, are specially made to go through different charging cycles to extend battery life span and protect batteries from overcharging.Thank you,AW

You're probably thinking of a charge controller, not an inverter. And yes, you always need a charge controller so you don't overcharge the battery with the solar panel

Depends on your battery set up...doubt one panel will get the job done. Works great for my RV though.

It may overcharge your battery though not likely.It does have a bypass diode which is only useful when connecting multiple panel in series. The diode has nothing to do with overcharge protection.You should consider adding a diode in series with the + lead to prevent leakage at night. Again this will have no effect on overcharge.It may be easier to add a charge controller.

Yes. If you read the comment below, you will see that I was/am correct.The panel MAY have a diode, which would prevent it from actively discharging your battery when the sun goes down, but the comment below seems to refute that. The other problem is that this panel will cook your battery, because it will apply voltage and current anytime that light shines on the panel. It will do this regardless of the state of charge of your battery... This will boil the electrolyte, and you'll be left with a 12V paper weight.

I had the same concerns about potentially overcharging the battery. Even though this model charges at a very low rate, nevertheless, Schmacher recommends also purchasing their "Solar Charge Controller" #SPC-7A. When time allows, I may give Schmacher a call and quiz their techs on whether or not a controller is really necessary on this lower output solar unit.

I would suspect it does not have overcharge or float mode to protect from overcharging. There are several out there that are made specifically for maintaining a full charged 12 Volt wet cell battery for around $10 to $15. I use one by Cen-Tech for an old Jeep I have to keep the battery charged.

I have successfully used it to keep my rv house batteries charged up during downtime. You should have no problems for your use. You will not need a controller as there will be no chance of overcharge with the small wattage.

You need to fully charged your Deep Cycle Battery. Connect your HQRP 30W Flexible Solar Panel and face it towards the sun where you have approx 8 to 10 hrs of sunlight daily . Also I have a Sunright 7 amp Solar Charge Controller for double protection of overcharging. I use it for my Battery Portable Solar Generator, and My RV's House Batteries (trickle charging)

What a great idea! You sure can hook this panel up to a car or marine battery for trickle charging. For an emergency charge you could get away with not using a controller. Just be sure to unhook the panel before the battery gets to 14.5 volts which will take a very long time with a 13.5 watt panel. This panel would be better served for maintaining a battery charge and you would need a controller for that. I did a quick experiment to verify and posted some pictures in the 'Product Images from Customers' section. All the items I used can be found on Amazon: Sunforce 7amp Charge Controller (I wasn't too impressed with this controller, for regular use the Sunforce 60031 10amp Digital Charge Controller is a nicer model): http://www.amazon.com/Sunforce-7-Amp-Charge-Controller/dp/B0006JO0XI/ref=sr_1_1?ie=UTF8&qid=1387406266&sr=8-1&keywords=sunforce+7amp+controller http://www.amazon.com/Sunforce-60031-Digital-Charge-Controller/dp/B001DZONCW/ref=sr_1_fkmr0_2?s=automotive&ie=UTF8&qid=1387413721&sr=1-2-fkmr0&keywords=Sunforce+10amp+ditital+controller Gino 2.1x5.5mm Male Jack DC Power Adapter: http://www.amazon.com/gp/product/B0058RLD9C/ref=oh_details_o03_s01_i00?ie=UTF8&psc=1 2.1mm DC Power Cord Coupler Female to Female: http://www.amazon.com/gp/product/B002IULV8U/ref=oh_details_o09_s00_i01?ie=UTF8&psc=1

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.

According to the manual, it is protected whether the battery or the solar panel is connected wrong.

This works as a battery maintainer, not a battery charger. If you want to charge a battery for a power inverter, you need a much larger solar panel. To put this in perspective, this provides around 2.5 watts maximum. The 12v power plug in most cars is capable of more than 100 watts. I have mine attached to a deep cycle RV battery and it will barely maintain the charge, even with the battery disconnected fro the trailer.

You can just hook it up +&-. Or you can get a charge controller that will desulfinate the battery, not overcharge and not discharge at night. There is lots of 'em available... Me, I like the Battery Tender 021-1162 Solar Panel Charger Controller

The nature of your question suggest you are looking for a battery "charger". If this is the case you will need more than the 5 Watts this panel can provide. With the 5 watts provided from this panel, you won't need allot of wiz's bang circuit breakers and meters. This panel dose a great job of keeping a fully charged battery in top shape all by it's self.

should work fine off a battery and using this to keep it charged.. shouldn't used it directly because of voltage fluctuations with clouds and weather.. will put out up to 6 amps in good sunlight...
